In the Network Map page, you can group multiple entities together for the better management and visibility. In the Network Map page, groups define a set of multiple entities. A group can also contain other groups. Groups are used to organize the entity list and to provide a context to the visualization in the network map. You can also use groups when searching for entities and paths.
vRealize Network Insight automatically creates some types of groups. For example, the system groups virtual entities inside the same physical host. You can also add your own groups, delete groups, and edit existing groups.
Note: You cannot edit or delete system-generated groups.
